A reciprocating engine is installed on the first floor of a building which can be modeled as a rigid rectangular plate resting on four elastic columns. The equivalent weight of the engine and the floor is 2000 lb. At the rated engine speed of 168 RPM, the operators experience large floor vibrations. To reduce the vibrations, a suspended spring mass system from the bottom surface of the floor is used. Assume the spring stiffness is 500 [lb/in]. Find the weight of the mass to be attached to absorb the vibrations.
